Answer:
10
Explanation:
Each time you want to move up the scale, the number is multiplied by 10. The opposite is true when moving down; you must divide by 10.

Acceleration = force / mass.
A = 100/50 = 2 m/s^2 .
Answer:

Explanation:
m = Mass of object = 
mg = Weight of object = 20 N
g = Acceleration due to gravity = 
v = Final velocity = 15 m/s
u = Initial velocity = 0
d = Distance moved by the object = 150 m
= Angle of slope = 
f = Force of friction
fd = Work done against friction
The force balance of the system is

The work done against friction is
.
Sun-earth-moon in a straight line. Earth in the 'middle'.
